WILLIAM JAMES, OF PROVIDENCE, RHODEISLAND DIESTOCK.

' Application filed May 5,

To aZZ' whom it may concern.

Be it known that I, lViLLIAM A. JAMES, a citizen of the Unitedv States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented new and useful Improvements in Diestocks, of whichthe following is" a specification;

This'invention relates to certainnew and useful improvements in diestocks" the primary object thereof is to provide a construction of diestocks in which. the-111511111 facture is greatly facilitated, and morespecifically by permitting a cutting tool to be moved or run into theyoke in order to form the two guide ways for the die and to properlyfinish such guide ways.

A further object of the invention is to provide a die stock which is soconstructed as to prevent the die from being placed wrong-side up, as intheusual yoke,which latter has the guide ways formed in its arms.

A still furtherobject of the invention is to provide a die stockwhichhas improved means of simple and positive character for holding the diesin the stock.

The invention still further aims to provide a die stock which is ofsimple and durable construction, and which also can be economically andexpeditiously produced.

Still further and other object will be later set forth and manifested inthe course of the following description.

In the drawings:

Figure 1 is a plan view of a die stock embodying in the invention, thehandles being shown in fragment;

Figure 2 is a front edge elevation;

Figure 3 is a section on line 33 of Figure 1, with the dies omitted toclearly show the guide ways;

Figure 4 is a top plan view of a modified form of the invention, partsbeing shown in fragment, and

Figure 5 is a front edge elevation of Figure 4.

In proceeding in accordance with the present invention the die stock hasa body composed of a yoke 1 and the usual handles 2. The yoke hasparallel arms 3 and are connected at their outer ends by a bridge 4,which latter is disposed slightly below the entrance into the yoke forthe dies D or below the plane of the yoke. By virtue of this dispositionof the bridge 4:, it will be seen that cutting or other tools employedin form ng and finishing t e guide ys 1922. Serial No. 558,566.

may be movedv or run into" the space between thearms 3 soastoconvemently and expeditiously form and. finish the guide D; and areimpinged thereagainst, so that-it will be readily seen the dies arepositively held within the yoke.

By referring to Figures 2 2111(1'3 of the drawings itwillbe seen thatthe guideways 5 are located closer to the bottoms of the arms 3 than tothe tops thereofsothat it is impossible to place the dies wrong side upin the yoke, and the latter are thus assured of being properlypositioned at all times when in operative engagement with the yoke.

In Figures 4. and 5 of the drawings a modified form of the invention isillustrated and wherein a different type of means is illustrated forlooking or latching the dies in the yoke. In this form of the inventiona pivoted bridge 20 is employed which formed to engage throughout thefront side of the foremost die D. The bridge is secured in place byscrews 21 which have operating heads 22, one end of the bridge 20 havinga U-shaped slot 23 which engages over the adjacent screw 21, so that itis merely necessary to loosen one of the screws in order to swing ormove the bridge 20 upwardly for the purpose of allowing the dies to bemoved out of the yoke.

In the form ofv the invention shown in Figures 1 to 3 the heads of theturn buttons are flattened or cut-away as depicted at 24, which is forthe purpose of causing said cutaway edges, upon partial turning of theturn-buttons 9 to lie in register with the inner side faces of the arms3 of the yoke, whereby upon such registry being effected, the dies maybe slid out of the guide-ways and new ones substituted. The turn buttonsare then merely given a partial rotation tov cause the uncut-away partsthereof to partly overlie the space between the arms of the ke a p ted.in F g re 1 and 2, l ps locking 0r latching the dies in the yoke. Itwill thus be seen that complete removal of the turn buttons is notnecessary, and in fact but partial rotation of each is required in orderto both latch and unlatch the dies.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is 1. A die stock including a yoke havingparallel arms, a rigid bridge connecting the outer ends of the arms anddisposed slightly below the plane of the lower sides of the arms,guide-ways formed on the inner side faces of the arms and located to oneside of the vertical center of the arms so as to preventmisplacement ofthe dies in the yoke, and turn-buttons having threaded shanks threadedinto the outer ends of the arms, the turn buttons having cut-outs ontheir heads, which cut-outs upon rotation of the turn buttons registerwith the inner side of the yoke to allow the dies to be slid out of thelatter, and upon further rotation have the uncut-away parts of theirheads in overlapping relation to the inner side faces of the arms of theyoke to latch the dies in the latter.

2. A die stock including a yoke having parallel arms, a rigid bridgeconnecting the outer ends of the arms and disposed slightly below theplane of the lower sides of the arms, guide-ways formed on the innerside faces of the arms and located to one side of the vertical center ofthe arms so as to prevent misplacement of the dies in the yoke, andturn-buttons having threaded shanks threaded into the outer ends of thearms.

3. In a die stock, a yoke having guide ways, said guide ways beinglocated so as to lie closer to one side of the longitudinal axis of theguide ways than to the opposite side of such axis, so as to preventmisplacement of the dies in the yoke, and means to hold the dies in theyoke.

4;. A die stock including a yoke having parallel arms, a rigid bridgeconnecting the free outer ends of the arms and havingits upper facedisposed slightly below the plane of the lower side faces of the arms,and

guide-ways formed on the inner side faces of the arms.

5. In a die stock, a yoke having parallel arms, guideways on the innerside faces of the arms formed to receive the dies, and turnable meansthreaded into the outer end of each of the arms and formed to latch thedies in the yoke in one position and in a second position to allow thedies to be re moved from the yoke.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
